I spend about an hour every time I want to use my system consisting of two speakers and a subwoofer.
Still I end up using my little Bose portable speaker to entertain my guests.
Either “no system found” or “system not configured” or only one speaker works at all - or everything drops again after 5 minutes.
I went to the dealer who told me that he “never heard of any issues” and it would be related to my WiFi. I got a 300Mbps network with an expensive Netgear router. My alarm, intercom, TV, and all other systems I use work perfectly but not that crap system of Sonos.
I regret I spent so much money on this system. At least I’m a good laugh for my guests when I tell them how much I paid for this.
